Crocodile longevity is not well established, but larger species like the Nile crocodile live longer, and may have an average life span of 70 to 100 years.
The life expectancy is probably only a few months. The life span probably is about 30-40 years.
40-70 year, depending on breed. I can't really find anything on the oldest age, but the spiecies itself was around when dinosaurs walked.
Also, what is the oldest known age of a crocodile?
